CPF06

Control Circuit Error (EEPROM memory Data Error)

The drive power supply was de-energized while a communication option entered a parameter Write command.

Set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire Initialization, 3-Wire Initialization] and initialize the drive.

An EEPROM peripheral circuit error occurred.

  • Re-energize the drive.

  • If the fault stays, replace the control board or the drive. For information about how to replace the control board, contact Yaskawa or your nearest sales representative.
Note:

  • The drive detects this error if there is an error in the data written to the drive EEPROM.

  • Do a Fault Reset to clear the fault.

  • Fault trace is not available for these faults.
